Well. You can say, "I need TP for my bunghole!!"
I refuse to call it "cornhole," it's a beanbag toss. I had never heard this term anyway until we were on a cruise a few years ago. DH and I were looking at the daily activity itinerary and he got all excited because after I told him what "Friends of Bill" stood for, he figured out "Friends of Dorothy" all on his own. He started howling and laughing because right after the "F.O.D." meeting, there was a "Cornhole Competition." Yes, he's immature...but I love him anyway.
